Weather in August

August is a hot and humid month in Iowa as the majority of the state registers temperatures in the 65°F (18.3°C) to 85°F (29.4°C) average range. The sun appears on the horizon at least for 22 days, while the rest of the month has cloudy skies with wet conditions. Humidity adds to the heat woes, as the temperatures seem to be higher than the actual readings. Summer rainfall is moderate to heavy at times and records 4" (102mm) to 5" (127mm) statewide.
In addition to thunderstorms, August is also vulnerable to tornadoes of varying intensities that strike Iowa in significant numbers during the summer. August is an excellent time to explore the Maquoketa Caves State Park, fish in the Okoboji Lakes, or go biking on one of the many beautiful trails in Iowa! There is plenty of wildlife in zoos and state parks in Iowa, and the tourist numbers rebound in August as the summer vacation attracts families to the state.
